Our Kohler Rialto Power-Lite (8 yrs old) has startedleaking from its pressurized tank. I was told by Kohlerthat this could not be fixed and I would have to buya new toilet. A plumber told me the same thing!Why can't this toilet be repaired?Kohler apparently stopped manufacturing pressurized tanksthemselves and will only give us a $75 rebate if we physicallytake the Rialto toilet to the original place of purchaseand purchase a new Kohler. This sounds ridiculous to mesince they apparently knew that they had designed a toiletthat was not meant to last and now I have to 1) hirea plummer to take out the faulty toilet 2)haul it down toHome Depot (who said that they don't want the toilet)3) purchase a new toilet by a manufacturer know to maketoilets that don't last long and 4) call the plumber back to install the new toilet!
